Works for typical puzzle/optimization Euros, but not for the games my gaming groups have enjoyed most. Anything involving politics, diplomacy, intrigue, back stabbing and the like just don't work solo. Nor do RPGs except for grindy munchkin-fests like CRPGs. IMHO, that human interaction is the reason to play games with other people.
